Preschool and Kindergarten Penguin Crafts, Activities, Lesson Plans, Games, and Printables.Penguins range in size from the fairy penguin which only gets about 9 inches tall to the emperor penguin which can reach heights of up to 3-4 feet. Although penguins are birds, they do not fly, at least not in the air. Penguins spend most of their time underwater looking for dinner (fish, squid, krill, and crustaceans). All penguins live below the equator, from the Galapagos Islands to Antarctica.
